A Paperboard Learning Aid for Trigonometry
AssistiveMath began in high school at the Kenya Science and Engineering Fair when our founder, Ron Pile, explored how visually impaired students could learn mathematics through simple and accessible learning aids. He adapted the hand-rule trick for learning sines, cosines, and tangents into a tactile learning aid. It was made from waste cardboard paper— therefore making it simple, portable, cost-free, and easy to replicate.
